Definitions
- This disclosure relates generally to systems and methods for minimally invasive medical procedures within a patient's body cavity. More particularly, embodiments of the present disclosure relate to devices and methods to identify the location of a target (e.g., a stone, foreign object, and/or tissue) within a patient's body.
- a target e.g., a stone, foreign object, and/or tissue
- Urolithiasis is a condition in which a kidney stone forms within a person's urinary tract.
- a kidney stone is a small hard stone that can cause pain, bleeding, obstruction, or infection.
- a kidney stone forms from deposits of calcium, phosphates, and urates.
- a treatment procedure for urolithiasis is kidney stone ablation using a mechanism such as a laser or lithotripter to ablate and/or fragment the kidney stone, after which the resulting fragments may be removed from the body and/or eliminated along with urine.
- a flexible fiber-optic endoscopic device delivers energy, such as, e.g., laser, radio frequency, ultrasound, etc., to the kidney stone.
- each energy source has an optimum range from its target. At this range, the energy source operates to achieve maximum disruption of the target stone. In addition, other factors, such as, geometry of the kidney stone and its precise location within the body cavity may affect effective fragmentation.
- the device may be damaged.
- the distal end of the energy delivery device may extend out from the distal end of a suitable introduction sheath, e.g., an endoscope, and if that end collides with the kidney stone, the energy delivery device and/or introduction sheath may be damaged.
- a suitable introduction sheath e.g., an endoscope
- Such damage may cause the delivered energy to be transmitted at undesirable locations, which may cause inadvertent damage to surrounding tissue.
- a physician must accurately detect the distance between the energy delivery device and the kidney stone.
- Endoscopic visualizing devices such as a camera or ultrasound device can help physicians roughly estimate the geometry and location of the kidney stone as well as the distance between the energy deliver device and the kidney stone.
- Visualizing devices have been shown to fall short of providing the degree of detail and precision required to control the urolithiasis procedure. Such inaccuracy may lead to complications or cause inadvertent damage to nearby tissue.
- Embodiments of the present disclosure provide a medical device for detecting an object within a patient's body.
- a medical device may include an elongate member having a proximal end, a distal end, and a lumen extending therebetween, wherein the elongate member may be configured for insertion into a patient.
- the medical device may also include a detection member configured to detect at least one of a location, geometry, or distance of a target relative to the distal end of the elongate member, the target being at least one of a stone, a foreign object, or a tissue within a body cavity.
- the detection member may include a transmitting element and a receiving element.
- the medical device may include one or more of the following features: the elongate member and the detection member may be independently steerable; the transmitting element may direct energy towards the target, and the receiving element may receive energy reflected from the target; the energy may be one of radar or acoustic energy; the transmitting and receiving element may be included within a single housing; the medical device may further include an energy delivery device; the energy delivery device may be a laser fiber; the detection member may be configured to detect at least one of a location, geometry, or distance of a target relative to the distal end of the elongate member based on energy reflected from the target; the medical device may be configured to communicate to a user the distance of the target relative to the distal end of the elongate member by a signal; and the signal may be one of a visual, tactile, and an audible signal.
- a sensing system may include an elongate member having a proximal end, a distal end, and a lumen extending therebetween.
- the elongate member may be configured to be inserted into a patient.
- the sensing system may also include a transmitting element carried within the lumen and configured to transmit energy from the distal end of the elongate member toward the target, and a receiving element carried within the lumen and configured to receive transmitted energy reflected from the target, wherein the target is at least one of a stone, a foreign object, or a tissue within a body cavity.
- the transmitting element may be configured to direct at least one of radar, acoustic, radiofrequency, and optical energy at the target; a control module configured to calculate at least one of a location, geometry, or distance of a target relative to the distal end of the elongate member based on energy reflected from the target; and the system may be configured to communicate to a user the distance of the target relative to the distal end of the elongate member by a signal; the signal may be one of a visual, tactile, and an audible signal.
- a method for detecting an object within a patient's body may include introducing a medical device into a body cavity.
- the medical device may include an elongate member having a proximal end, a distal end, and a lumen extending therebetween, wherein the elongate member may be configured to be inserted into a patient.

Description
- This application claims the benefit of U.S. Provisional Application No. 61/785,320, filed Mar. 14, 2013, the disclosure of which is incorporated herein by reference in its entirety.
- This disclosure relates generally to systems and methods for minimally invasive medical procedures within a patient's body cavity. More particularly, embodiments of the present disclosure relate to devices and methods to identify the location of a target (e.g., a stone, foreign object, and/or tissue) within a patient's body.
- Urolithiasis is a condition in which a kidney stone forms within a person's urinary tract. A kidney stone is a small hard stone that can cause pain, bleeding, obstruction, or infection. A kidney stone forms from deposits of calcium, phosphates, and urates. A treatment procedure for urolithiasis is kidney stone ablation using a mechanism such as a laser or lithotripter to ablate and/or fragment the kidney stone, after which the resulting fragments may be removed from the body and/or eliminated along with urine. A flexible fiber-optic endoscopic device delivers energy, such as, e.g., laser, radio frequency, ultrasound, etc., to the kidney stone.
- The distance between the energy delivery device and the kidney stone affects the amount of energy effectively transmitted, which in turn affects quality of fragmentation. Generally, each energy source has an optimum range from its target. At this range, the energy source operates to achieve maximum disruption of the target stone. In addition, other factors, such as, geometry of the kidney stone and its precise location within the body cavity may affect effective fragmentation.
- Further, if the energy delivery device is advanced too close to the kidney stone, the device may be damaged. During operation, the distal end of the energy delivery device may extend out from the distal end of a suitable introduction sheath, e.g., an endoscope, and if that end collides with the kidney stone, the energy delivery device and/or introduction sheath may be damaged. Such damage may cause the delivered energy to be transmitted at undesirable locations, which may cause inadvertent damage to surrounding tissue. Thus, a physician must accurately detect the distance between the energy delivery device and the kidney stone.
- Endoscopic visualizing devices, such as a camera or ultrasound device can help physicians roughly estimate the geometry and location of the kidney stone as well as the distance between the energy deliver device and the kidney stone. Visualizing devices, however, have been shown to fall short of providing the degree of detail and precision required to control the urolithiasis procedure. Such inaccuracy may lead to complications or cause inadvertent damage to nearby tissue.
- Therefore, there exists a continuing need for devices that can accurately communicate to an operator the distance between the energy delivery device and the kidney stone while performing ablation and/or fragmentation of the kidney stone.
- Embodiments of the present disclosure provide a medical device for detecting an object within a patient's body.

The elongate member may be configured to be inserted into a patient. The sensing system may also include a transmitting element carried within the lumen and configured to transmit energy from the distal end of the elongate member toward the target, and a receiving element carried within the lumen and configured to receive transmitted energy reflected from the target, wherein the target is at least one of a stone, a foreign object, or a tissue within a body cavity.
- Various embodiments of the system may include one or more of the following features: the transmitting element may be configured to direct at least one of radar, acoustic, radiofrequency, and optical energy at the target; a control module configured to calculate at least one of a location, geometry, or distance of a target relative to the distal end of the elongate member based on energy reflected from the target; and the system may be configured to communicate to a user the distance of the target relative to the distal end of the elongate member by a signal; the signal may be one of a visual, tactile, and an audible signal.

The method may also include transmitting an energy signal from the transmitting element, receiving a reflection of the transmitted energy signal with the receiving element, and processing the received reflection to determine at least one of the location, geometry, or distance of the target relative to the elongate member.

In the illustrated embodiment, theelongate member 102 includes a substantially circular cross-sectional configuration, with a similarly configured hollowinterior lumen 108, although other shapes may be used. The shape, size, length, and structure of theelongate member 102 may be varied depending upon the particular implementation and intended use. For example,elongate member 102 may be rigid along its entire length, flexible along a portion of its length, or configured for flexure at only certain specified locations. Theproximal end 104 ordistal end 106 may include geometrical structures, such as, rounded or beveled terminal ends and/or faces, to reduce trauma and irritation to surrounding tissues. In addition, theelongate member 102 or a portion of it may be selectively steerable. Mechanisms such as, motors, hydraulic or any other actuators may be used to selectively steer theelongate member 102. -
Elongate member 102 may be formed of any suitable material having sufficient flexibility to traverse body cavities and tracts, such as, fiber or wires that may be woven or braided together using synthetic plastics, fiber, or polymers. Alternatively,elongate member 102 may be rigid or semi-rigid, formed from materials, such as, stainless steel or the like, including shape memory alloys, such as, e.g., Nitinol. In general,elongate member 102 may be made of any suitable material that is compatible with living tissue or a living system. Suitable materials may include nitinol, ePTFE, fabric, and suitable nickel and titanium alloys. Those in the art are well aware of the range of suitable and available materials. - Further, the
elongate member 102 may include any suitable coating or covering. For example, the outer surface may include a layer of lubricous material to facilitate insertion through a body lumen or surgical insertion. Further,elongate member 102 may be coated with biocompatible antibacterial and/or anti-inflammatory substances, if desirable. -
Elongate member 102 may be provided with any of a wide variety of end-effector devices for performing a range of tasks including fragmenting kidney stones. In an embodiment of the present disclosure, theablation tool 120 may be configured as a laser fiber disposed within achannel 112 b and connected to a laser system (not shown) throughports 124. The laser system directs laser energy through the laser fiber 120 (ablation tool), and this energy may be directed longitudinally or laterally from thedistal end 106. Alternatively, thelaser fiber 120 may be formed integrally into theelongate member 102.Laser fiber 120 can be sized in an approximate range of about 200 to about 500 microns for the desired purpose. The laser system itself may be, for example, a coumarone-based pulsed dye laser, or a laser formed of alexandrite, Ho:YAG, or Nd:YAG. - To facilitate ablation, embodiments of the present disclosure may employ the
detection member 118, located at thedistal end 106 ofelongate member 102. In general, thedetection member 118 directs some form of wave energy, such as radar, sonar, radiofrequency, radiation, and/or optical energy, at a target stone and receives reflected energy from the stone. In some embodiments, the energy may be delivered as mechanical vibration and/or thermal energy, which may be delivered continuously or in a pulsed fashion. Acontrol module 122 includes a computing device that analyzes the reflected energy to determine the location and/or geometry of the target as well as the distance between the target anddistal end 106. In one embodiment, for example, thecontrol module 122 may be configured to detect changes in reflected energy profiles. For example, energy (e.g., laser or sound energy) delivered in a pulsed fashion may be reflected a differing or varying rates or altogether randomly when compared to energy delivered continuously. Those of ordinary skill in the art will understand that the reflected energy that is received bydevice 100 may be in a form that is different than the form of the transmitted energy. For example, a laser energy delivered to ablate a stone may be received as light, heat, and sound energy, each of which may be analyzed to identify one or more characteristics of the stone. In the illustrated embodiment, the system is configured as a radar-based device. The following sections describe the system member in greater detail. - In some embodiments, the
medical device 100 may additionally or alternatively include a plurality of temperature sensing elements for detecting thermal energy reflected by a stone, for example. The temperature sensing elements may include thermocouples, thermistors, or any or suitable devices known in the art. Further,medical device 100 may additionally or alternatively include a projecting member (not shown), such as, e.g., a small wire, that extends distally ofdistal end 106. The projecting member may be configured to engage a stone or other material disposed in a patient's lumen, thereby detecting the presence or absence of stone via, for example, mechanical engagement or vibration. -
FIG. 2 represents a longitudinal cross-section of a distal portion of themedical device 100. Thedetection member 118 may include, but is not limited to, anelongate tube 202, a radar-transmittingantenna 204, and a radar-receivingantenna 206, both disposed at the distal end of theelongate tube 202. Although the depicted embodiment illustrates the radar-transmittingantenna 204 and radar-receivingantenna 206 as separate, discrete structures, those of ordinary skill in the art will recognize that the radar-transmittingantenna 204 and radar-receivingantenna 206 may be provided within a single, multi-functional component. Theelongate tube 202 may be slidably disposed within achannel 112 a. - The radar signal is generated in the
control module 122. Thecontrol module 122 may be disposed internally or externally to themedical device 100. In the illustrated embodiment, thecontrol module 122 is disposed externally to themedical device 100 and patient. Thecontrol module 122 may generate the radar signal using a radar generation circuitry, which may be any electronic circuit that may generate radar signals of a desired frequency band. The radar generation circuit may include electronic devices such as crystal oscillators, POT (Power Oscillation Transmitters), PAT (Power Amplifier Transmitters), VCO (Voltage-Controlled Oscillator) or a PLL (Phase Lock Loop) and the like. Thecontrol module 122 may also include a radar receiver circuit. Anappropriate communication medium 208, such as copper wire, coaxial cable, or wireless transmission, may link theantennae module 122. Thecontrol module 122 and thecommunication medium 208 will be discussed later in greater detail. - The
elongate tube 202 may be the distal portion of theelongate member 102, or it could be a separate tubular device carried withinelongate member 102 and deployed in the proximity of thetarget kidney stone 210. In that scenario, theelongate tube 202 may be a polymeric or rubber fiber or cable covering the components of thedetection member 118, to protect thedetection member 118 from the fluid medium generally present within a body cavity.Elongate tube 202 may or may not include one or more lumen/channel therethrough. In embodiments whereelongate tube 202 includes one or more lumens, a distal end portion ofelongate tube 202 may include one or more openings. Theelongate tube 202 may include mechanisms such as control lines or wires, or similar actuators, allowing an operator to steer its distal end within the body cavity. This steerability may be independent of the steerability of theelongate member 102, permitting an operator to steer the distal end of theelongate tube 202 around bends or into branching passages separately from the general control of theelongate member 102. - As discussed, the
detection member 118 may include the radar transmitting and receivingantennae distal end 106 ofelongate tube 202. The radar transmitting and receivingantennae detection member 118 and the nature of the target to be identified. - The frequency and wavelength of the transmitted and received radar by the transmitting
antenna 204 and receivingantenna 206 respectively may depend upon the size and location of the desired target, for example, thekidney stone 210. In general, the diameter of thekidney stone 210 may be greater than the wavelength of the radar transmitted, to detect the size, location, and geometry of thekidney stone 210 with adequate resolution. In a typical renal cavity, thekidney stone 210 may range from a few millimeters (mm) to a few centimeters (cm) in diameter. Thus, radar having a wavelength in the range of a few mm to a few cm may be used to detect thekidney stone 210. As radar may be generally categorized into specific frequency bands, some suitable frequency bands that may be used for detection ofkidney stone 210 may be mm (frequency range-40-300 GHz, wavelength range −1 mm-7.5 mm), V (frequency range-40-75 GHz, wavelength range −4 mm-7.5 mm), W (frequency range-75-110 GHz, wavelength range −2.7-4.0 mm), UWB (frequency range-1.6-10.5 GHz, wavelength range −18.75 cm-2.8 cm). - In principle, the
detection member 118, which is configured as radar may operate by transmitting, e.g., radio waves using the transmittingantenna 204. The radar may be reflected from thekidney stone 210 and is received by the receivingantenna 206. Thecontrol module 122 then analyzes the characteristics of the received radar in connection with the characteristics of transmitted radar to detect size, location, and geometry of thekidney stone 210 using a radar detection algorithm. Thecontrol module 122 may use a number of radar detection algorithms known in the art, such as pulse radar (boundary scattering transforms), synthetic aperture radar (SAR), or inverse synthetic aperture radar (ISAR) to detect thekidney stone 210. The radar detection algorithm may include signal processing functions including, but not limited to, removal of noise artifacts, amplification, etc. - As described earlier, the
communication medium 208 operationally connects the transmittingantenna 204 and the receivingantenna 206 to thecontrol module 122. Thecommunication medium 208 may be any wired or wireless connection, such as, copper wires, optical fiber, WIFI, Bluetooth or infrared connection. For example, thecommunication medium 208 may be a length of copper wires operationally connecting the transmittingantenna 204 and the receivingantenna 206 to thecontrol module 122. - In addition, a suitable coating and/or covering may be applied on the
detection member 118. For example, the outer surface may include a layer of lubricous material to facilitate its deployment through thechannel 112 a. Further, thedetection member 118 may be coated with a biocompatible material such as Teflon. To inhibit bacterial growth in the body cavity, an outer surface ofdetection member 118 may be coated with an antibacterial coating. - The
control module 122 may implement the desired radar detection algorithm, and control a number of operations, such as, transmission, reception, and processing of the radar signals. In addition, thecontrol module 122 may control other auxiliary devices and functions, such as, an output display or an alarm. Further, thecontrol module 122 may send control signals to actuate other endoscopic medical tools, for example a resection device, an ablation device, or a visualization device. - The
control module 122 may include a computing device (not shown) and multiple peripheral tools (not shown). The computing device may be a microcontroller circuit or a microcomputer running custom software. Among other functions, the computing device may control thedetection member 118 as well as any signal processing functions. Further controls may extend to other peripheral tools, such as a display device, an audio output device, or an actuator device. The display device may be a CRT monitor, a LCD monitor, or similar device. - In addition, the
control module 122 may employ an audio signal to provide direct system performance feedback. It is desirable, for example, to position the distal tip of theelongate tube 202 at an optimal distance from a target stone, and that distance can be indicated by an audio signal. In one embodiment of the disclosure, thecontrol module 122 determines the distance between the distal tip and the target stone, compares that distance to an optimal distance, and indicates the difference value by outputting an audio signal whose pitch, timbre, or rhythm varies with the difference value. The signal may be a series of beeps, for example, whose spacing or pitch varies as the distal tip approaches the optimum position relative to thekidney stone 210. Because operators particularly seek to avoid a collision between theelongate tube 202 and thekidney stone 210,control module 122 may be programmed to sound an alarm when the separation distance goes below a given value. - Further, the
control module 122 may control other tools present in other channels 112. For instance, thecontrol module 122 may trigger thelaser fiber 120, or other supporting tools required to accomplish a medical procedure. In addition, thecontrol module 122 may include additional equipment, such as, motors or actuators to control other subsidiary operations. - In an alternative embodiment of the present disclosure, the
detection member 118 may utilize a sonar transmitter and receiver to detect one or more of the location, geometry, and/or distance of a target from thelaser fiber 120. Similarly, another alternative embodiment may employ a LIDAR system as thedetection member 118. Further, a person skilled in the art may find many systems and devices that may be used as thedetection member 118. -
FIG. 3 depicts themedical device 100 within aurinary tract 300, illustrating an exemplary method of using themedical device 100 to fragment and assist in the removal of thekidney stone 210. An operator may insert theelongate member 102 within theurinary tract 300 though a natural orifice or an incision. The operator may then maneuver theelongate member 102 within range of thekidney stone 210, employing the techniques of the present disclosure to prevent thedistal end 106 from contacting the stone, while at the same time ensuring that thedistal end 106 and/or the distal end of the energy delivery device is disposed at a location optimally spaced from the target. - Returning to
FIG. 2 , thecontrol module 122 generates a signal and sends it to the transmittingantenna 204 to transmit a radar signal from thedistal end 106 throughopening 116. The transmitted radar signal impinges on the surrounding cavity and reflects signals back to the receivingantenna 206 throughopening 116. Depending upon the wavelength, intensity, and angle of the transmitted and reflected radar signals, the location, geometry, and/or distance of thekidney stone 210 can be determined. Specifically, receivingantenna 206 receives the reflected radar signals and passes it on to the computing device within thecontrol module 122 for processing. - The computing device may then calculate the location, geometry, and/or distance of the
kidney stone 210 from thedistal end 106 using one or more radar detection algorithms. The computing device may further generate any graphical, numeric, or audio output at any attached output device within thecontrol module 122. The graphical or numeric output generated by the computing device may be displayed on the display device, such as an LCD monitor, to aid the operator in positioning thedistal end 106 relative to thekidney stone 210. During that process, as discussed above, an audio signal may vary in pitch, timbre, or rhythm, guiding the operator toward the optimum position. The audio signal may also sound an alarm if thedistal end 106 approaches to within a predetermined danger distance from thekidney stone 210, thereby assisting to prevent inadvertent collision with thekidney stone 210. - Referring to
FIG. 3 , the operator may thus position thedistal end 106 at an optimum distance and at an optimum angle from thekidney stone 210 for efficient ablation. The operator may then ablate thekidney stone 210 using the laser fiber 120 (ablation tool). The laser energy may exit theelongate member 102 throughopening 116. - After performing the ablation, the
detection member 118 may confirm successful ablation of thekidney stone 210, employing the radar signals to determine the size of any remaining of theoriginal kidney stone 210. After completion of the ablation and related procedures, the operator may finally retract themedical device 100 from theurinary tract 300. - It may be noted that the use of the
medical device 100 mentioned above is an exemplary description of use and a person skilled in the art may envision other uses for themedical device 100. For instance, the disclosed device may be used in the coronary artery to detect plaque buildup. Thedetection member 118 may be used to detect location, size, and/or geometry of the plaque buildup within the coronary artery while a medical tool may be inserted within channels 112 to remove the plaque buildup. Other instances may include application of the disclosed device in other body cavities, such as, gastrointestinal tract or the biliary system. - Embodiments of the present disclosure may be used as described herein or in combination with any suitable imaging modality known in the art. For example, the principles of the present disclosure may be used in conjunction with one or more internal and/or external imaging modalities (e.g., ultrasound) to enhance the detection of, e.g., stones with a patient.
- Embodiments of the present disclosure may be used in any medical or non-medical procedure, including any medical procedure that requires detection of location, geometry, and/or distance of a target from the
medical device 100 within a body cavity. In addition, at least certain aspects of the aforementioned embodiments may be combined with other aspects of the embodiments, or removed, without departing from the scope of the disclosure. - Other embodiments of the present disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the embodiments disclosed herein. It is intended that the specification and the examples described herein be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
